CH Precision is an M1.1. 2 x 200 W 8 Ohm power supply, the operation of the driver part is, of course, in pure class A, a fully discrete element base, a 2,200 VA transformer, a 250,000 UF capacitor bank – it can take a long time to list.
Doubled the power supply capacity (vs. M.1.1) High End amp offers bandwidth up to 500kHz and delivers 2 x 550 Wt (4 Ohms load)!
